A method of forming embossed edges around holes in a metal plate, wherein the plate is provided with a pattern of holes and is then arranged on a support such that the edge portions of the plate around said holes are unsupported and wherein the portions are simultaneously subjected to a uniformily distributed pressure to press them out of the plane of the plate on the side adjacent the support, the edge faces of the portions thereafter being ground, polished or lapped parallel to the plane of the plate. A shear plate 31 having holes 32 is positioned on a jig 34 having complementary holes 35, the mouths of which have a 60 degrees countersink, the largest diameter of which is greater than that of the holes 32. The minimum width between holes is not more than 0À5 mm. and the thickness of the plate is not more than 0À25 mm. A pressure plate 37 provided with an elastic material layer 38 of, e.g., rubber, is lowered into contact with the plate 31 and the unsupported edge portions of the holes 32 are bent downwardly against the countersinks 36. The plate is removed and the edge surfaces of the holes are ground, polished or lapped parallel to the plane of the plate. In a modification the elastic layer is provided with a plurality of spherical bodies, e.g. steel balls, having a diameter greater than the holes 32 which deform the unsupported edges of the holes. The shear plates thus formed are suitable for use in an electric dry-shaving apparatus.

Title: Manufacture of azo-dyestuffs and chromium compounds thereof
IPC: C09B45/16
Filed: 1922-11-11
Abstract: o-Amino-o-oxyazo dyes are prepared by coupling an o-diazo-phenol not containing a nitro group, with a naphthylamine or a derivative or substitution product which is capable of orthocoupling and which contains no hydroxyl group or further amino group; the same products are obtained by converting the diazo components into O-acidyl derivatives, diazotizing and coupling, and then saponifying.  The products dye wool in orange shades changed to green by after-chroming and to bluish-red to bordeaux by after-coppering; by treatment with agents yielding chromium the dyestuffs yield chromium compounds which dye wool in fast green tints.  According to examples (1) 2-diazo-1-phenol-4-sulphonic acid is coupled with b -naphthylamine hydrochloride, and the double compound of the dyestuff with b -naphthylamine decomposed with caustic soda; the same dyestuff is obtained by coupling 2 - diazo - 1-phenol-p-toluenesulphonic-ester-4-sulphonic acid with b -naphthylamine and saponifying; it is converted into a chromium compound by boiling with chromium formate; (2) diazotized 4-chlor-2-aminophenol-5-sulphonic acid is coupled with 1-naphthylamine-4-sulphonic acid and the product boiled with hydrated chromium oxide, filtered and evaporated.  Dyestuffs from the following pairs of compounds are also described:-4-chloro-2-aminophenol and 2-naphthylamine-6-sulphonic acid or 5 : 7-disulphonic acid; 4-chlor-2-aminophenol-5-sulphonic acid and b -naphthylamine or its o -methane-sulphonic acid; 4-methyl-2-aminophenol-5-sulphonic acid and b -naphthylamine.

Abstract: 159,994. Allen, R. Dec. 10, 1919. Piston packing.-In a piston packing-ring of the type having one or more joints, each covered by side plates and expanded by a wedge, the side plates and the wedge are independently operated by springs, and the parts are secured together to prevent separation when removed from the piston. The joint of the ring e, Fig. 1, is covered by segments c on a tube a, the expanding wedge b being situated between the segments c. The tube a is pressed radially outwards by an involute spring a<1>. One end of the spring a<1> is formed with a flange entering a groove in the tube a, while the other end grips the lower end of a spring b<1> which presses the wedge b outwards. The outer end of the spring b<1> grips a groove in the stem b<2> of the wedge b. The springs a<1>, b<1> may be formed in one, as shown in Fig. 18, the lower end of the spring b<1> being wound backwards in the reverse direction to form the spring a<1>.

IPC: B21C37/06
Filed: 1926-12-07
Abstract: 280,382. Wheelwright, T. S. Dec. 7, 1926. Pipes and tubes.-In a method of manufacture of hollow iron bars for stay bolts &c. comprising bundling weldable metal round a hollow metal core, packing the core with refractory material, heating the bundle to a welding temperature, rolling it to desired size and removing the refractory core, torsion of the bundle and distortion of the axial hole is avoided in the rolling operation by the provision of polygonal or non-circular passes. In the arrangement of Fig. 1 the metal bars C are bundled between the hollow metal core B and an outer tube A, and in Fig. 2 the bars are packed between the core B and two semi-cylindrical metal sheets D, the whole being bound together by wire E. In another arrangement, Fig. 3, flat bars F are set to polygonal outline and the space between them is packed with bars C round the core B and the whole secured by wire binding. E, whilst in a further arrangement the bars are merely bundled round the core and bound with wire. Any suitable refractory material may be employed for packing the core for example silica sand, soapstone, graphite, carborundum sand, zircon sand, or electrically sintered alumina or magnesia. Twisting of the bar during rolling is prevented by employing polygonal passes H and the bar J is fed in with its flats in the same planes as the flats of the pass; a larger number of passes is used to minimize distortion, sixteen or twenty being preferred, and the last pass K is round to give the bar its final form. The refractory filling G is removed from the finished bar M, Fig. 7, by revolving the bar in a lathe and advancing in the bore a metal tube N connected to a compressed air supply.

A traversing shoot 8 comprises a rigid rectilinear guideway 1, carriage 3 displaceably mounted on the said guideway and through a load-transmitting connection which permits relative movement attached to the shoot at or near its discharge end between the carriage and the shoot ; and shoot traversing mechanism including a driving member 14 which drives the carriage or the shoot through a connection 12 permitting relative movement in a vertical direction between said member on the one hand and said carriage or shoot on the other hand. Figs. 1 and 3. Shoot which is pivoted at its upper end is connected at 12 to the carriage 3 which is traversed over the guideway 1 by means of driving screw 14 and nut 16. Carriage 3 carries rollers 4 and 5 which press against the guideway 1 and run there-along. The carriage 3 carries nut 16 which engages any one of the two screws 15, Fig. 2 (not shown), oppositely cut into rotating screw 14, and also carries rotatable bolt 10 which mounts a pair of rollers 12 which run along guide 13 fixed to the lower part of shoot 8. Rotation of the screw 14 drives the nut 16 and through bolt 10 and rollers 12 traverses the shoot along the guideway 1, the rollers 12 running along guide 13 and permitting shoot 8 to traverse the guideway 1. Thus, material passing down the shoot is distributed evenly over the width of hopper 2. Alternatively, the screw 14 and driving nut 16 may be separate from carriage 3, the carriage being connected by rollers 12 to shoot 8 and nut 16 being connected by similar rollers to a separate guide fixed higher on shoot 8. Figs. 3 and 9. The nut 16. The nut 16 is formed with side channels 18, which channels engage with and slide within vertical members of the carriage so that the nut is drivingly connected to the carriage but is permitted movement in a vertical plane. The screw 14 passes freely through the longitudinal hole 17 cut into the nut and the driving connection is made by lug 24 which enters the hole 17 and may be kept in contact with the screw either by its own weight or, as shown, by a removable cap. Side channels 18 diverge as shown to permit angular "give" of the nut.
